How do you obtain a Drawable object from a resource id in android package?

I need to get a Drawable object to display on an image button. Is there a way to use the code below (or something like it) to get an object from the android.R.drawable.* package?

for example if drawableId was android.R.drawable.ic_delete

mContext.getResources().getDrawable(drawableId)

The best way is

 button.setBackgroundResource(android.R.drawable.ic_delete);

OR use the below code for Drawable left, top, right, bottom. I'm setting drawable left in this case.

int imgResource = R.drawable.left_img;
button.setCompoundDrawablesWithIntrinsicBounds(imgResource, 0, 0, 0);

and

getResources().getDrawable() is now deprecated

From API 21 `getDrawable(int id)` is deprecated

So now you need to use

ResourcesCompat.getDrawable(context.getResources(), R.drawable.img_user, null)

But Best way to do is :

- You should create one common class for getting drawable and colors because if in future have any deprecation then you no need to do changes everywhere in your project.You just change in this method 
import android.content.Context
import android.graphics.drawable.Drawable
import androidx.core.content.res.ResourcesCompat

object ResourceUtils {
    fun getColor(context: Context, color: Int): Int {
        return ResourcesCompat.getColor(context.resources, color, null)
    }

    fun getDrawable(context: Context, drawable: Int): Drawable? {
        return ResourcesCompat.getDrawable(context.resources, drawable, null)
    }
}

use this method like :

Drawable img=ResourceUtils.getDrawable(context, R.drawable.img_user)
image.setImageDrawable(img);

Following a solution for Kotlin programmers (from API 22) 

val res = context?.let { ContextCompat.getDrawable(it, R.id.any_resource }

As of API 21, you should use the getDrawable(int, Theme) method instead of getDrawable(int), as it allows you to fetch a drawable object associated with a particular resource ID for the given screen density/theme. Calling the deprecated getDrawable(int) method is equivalent to calling getDrawable(int, null).

You should use the following code from the support library instead:

ContextCompat.getDrawable(context, android.R.drawable.ic_dialog_email)

Using this method is equivalent to calling:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
    return resources.getDrawable(id, context.getTheme());
} else {
    return resources.getDrawable(id);
}

As of API 21, you could also use: 

   ResourcesCompat.getDrawable(getResources(), R.drawable.name, null);

Instead of ContextCompat.getDrawable(context, android.R.drawable.ic_dialog_email)

Drawable d = getResources().getDrawable(android.R.drawable.ic_dialog_email);
ImageView image = (ImageView)findViewById(R.id.image);
image.setImageDrawable(d);
